Programming

I mostly blog about solutions I’ve made for problems I’ve encountered during my workday. The stack we use at Wehkamp is huge, so there’s always an interesting topic to blog about and many programming challenges to deal with. My main specialty is backend (.NET Core / ASP.NET / C#), but I do my fair share of Node.js and Python.`

Simple Python code to send message to Slack channel (without packages)

Last week I was working on a Databricks script that needed to produce a Slack message as its final outcome. I lifted some code that used a Slack client that was PIP-installed. Unfortunately, I could not use the package on my cluster. Fortunately, the Slack API is so simple, that you don’t really need a package to post a simple message to a channel. In this blog I’ll show you the simplest way of producing awesome messages in Slack.

AWS Lambda Size: PIL+TF+Keras+Numpy?

At Wehkamp we’ve been using machine learning for a while now. We’re training models in Databricks (Spark) and Keras. This produces a Keras file that we use to make the actual predictions. Training is one thing, but getting them to production is quite another!

The main problem we’ve faced was that it was too big to actually fit into a lambda. This blogs shows how we’ve dealt with that problem.
